Abstract: A display system includes a display and a detector configured to detect an orientation of the display. The display system includes a display source image generation unit configured to generate a display source image including a first image and a second image related to this first image; and a visual field image display unit configured to display the first image in a first display region of the display and display the second image in a second display region of the display. The visual field image display unit is configured to set a predetermined fixed region of the display as the first display region when a display mode associated with the first image is a first display mode, and determine the first display region according to the orientation of the display when the display mode is a second display mode.
